CT can inside home

[pdickerson]

Indoor CT cans are the norm here. I have one in my house. I have never found one that was not sealed, and I would call it out if I did.

Let me add one more item related to the CT's

there is one golden rules with CT's is never open the CT's lead while it is under the load.

if you open the CT's leads what will happend it they will build up insane amout of voltage and can blow the CT's [ myself i did see few blow up by either careless or corroded connections ]

Merci , Marc

Marc,

It is probably a good idea to make an even broader statement.....if you can help it refrain from opening ANY connection like that with a load being drawn on it if you help it. Opening contacts with a large amp draw for example can cause one heck of an arc.....bussman fuses has a nice video on that.....I will see if I can find it.

Paul :

I do agree with your statement.

but let you know that i allready see some pretty good arc flashover while disconnecting well loaded system espcally true with Meduim voltage system [ i work on 4160- 7200 volt system from time to time ]
the last arc flash when i was disconnecting a 150 amp Med voltage fuse that arc can jump much as 2 -4 feet after breaking it open.

Yes i did remember seeing the veido from Bussman fuse co.

Prettty nasty one i did see

Merci , Marc


P.S. Paul i am well verised with both USA and France electrical codes just let you know head up with this
